Description

[Detailed Description of the Invention] The present invention relates to a foldable insect-proof screen door suitable for use in conjunction with sliding door fittings.

Traditionally, insect screens have been used by stretching them over a frame and fitting them into window frames, etc., so if they are used by fitting them into one movable part of a sliding door, they can be used, for example, in high-rise houses. It is very inconvenient to have to remove the screen door each time you enter or exit the balcony, and when it is not in use, such as during winter, it requires a large space to store, which is inconvenient and difficult to pull. When used in a window frame with a sliding door and a separate screen rail, there is a large gap between the screen door and the sliding door in the direction of movement when the sliding door is open. There are drawbacks, such as the fact that insects can enter through the gaps even when the screen door is attached, making it impossible to act as an insect repellent.

In order to overcome these drawbacks, a system has already been proposed in which an insect screen is drawn out when the sliding door is opened in conjunction with the sliding door.

However, these devices are designed to require a winding mechanism to dispose of this feeding netting, and a special frame body must be assembled into the window frame in advance. Therefore, even if it is effective when forming a new window frame, there is a problem in that it cannot be attached to an existing window as is.

With this invention, even existing windows can be attached to the outdoor side, and even when the sliding door is opened half-open, it can be installed securely without creating a gap between the sliding door and the sliding door. To provide a foldable interlocking screen door which can be interlocked and further has the function of being able to be stored away from the door and low in bulk in a corner when not needed.

Below, this will be explained in detail with reference to an embodiment of a large sliding window.
To install the window frame on the outdoor side, use a base frame (in the case of an aluminum sash, a base frame is generally made of wood) and place the screen door guide support 10, 10' vertically parallel to the inside. The mounting seat 11 is bent along the edge in the direction opposite to the receiving surface 12 at an appropriate height, and is fixed with wood screws or nails. Both are made flat and slightly wide,
At its outer edge, there is an edge piece 1 of an appropriate height perpendicular to the receiving surface.
3 is formed over the entire length of both guide supports 10 and 10', and a guide rail 14 with an appropriate width opening 14' in the center of the opposing surfaces is attached approximately on the center line of the receiving surfaces of both guide supports 10 and 10'. A so-called accordion-shaped screen door 2 is formed by sliding a guide element 25 on both guide rails 14, 14 and bending it to an appropriate width between both guide supports 10, 10' to form a zigzag shape.
It was equipped with 0.

This screen door 20 is made of a synthetic resin net so that the maximum folded width is approximately the same as the width of the receiving surface 12 of the guide support 10 or 10'. The ends of the net 21 are sandwiched from both sides by plate pieces 22 having a length narrower than the width of the plate 22 and fixed together, and the support piece 26 of the guide 25 that slides on the guide rail 14 is attached in the center using machine screws 27 or the like. Each folded portion 21' of the net 21 is shaped into a curved state without any creases as shown in FIG. Either a brush section 23 is provided so that only the warp threads are in contact with the receiving surface 12 except for
1, so that the screen door 20 does not create a gap when moving with respect to the receiving surface of the guide support.

The screen door 20 is long enough to completely cover the opening surface of one of the sliding doors when it is fully opened, and a narrow strip is placed at both ends of the screen door over its entire length. The plate 24 is fixed, and a removable fixing means for either the sliding window or the window frame is attached thereto.

An example of this fixing means is as shown in FIG. 4, in which the loop side tapes 28 of pressure-bonding fasteners are attached at appropriate intervals to the outer surface of the vertical frame 2' of the house 2 at multiple locations using adhesive, for example. The end on the side of the screen door 20 is a free part 21' which is extended by an appropriate dimension from the other bent surface part.
The end edge is sandwiched with a thin band plate 24.24 over the entire length in the vertical direction with an appropriate width, and a hook piece is provided on the inner surface of the plate to engage and lock the loop tape 28 on the door 2 side. The hook tape 28' of the implant is fixed so as to correspond to the loop tape 27.

In addition, on the fixed side of the screen door 20, a connecting member 31, which connects the upper and lower guide supports 10° and 10' and has a cross-section shape that becomes the storage part 30 when the screen door 20 is folded, is attached to the inner end surface in the same manner as the movable side fixing means. It is removably fixed using a crimp-type fastener.

In addition, the fixed side is connected to the connecting material 31 and the edge is attached to the band plate 24.2.
4, or the upper and lower guide support plates 1
0.10' may be passed through the core frame and fixed to this. On the movable side, a fitting groove is provided in advance in a part of the door frame, and an elastic strip that can be fitted into this is attached to the edge of the net. It is possible to optionally adopt a method in which the two are attached to each other and the two are fitted together and fixed in a removable manner.

33 is a connecting plate attached to the side opposite to the screen door storage side.

Since the screen door of the present invention is constructed in this way, when the screen door 20 is used, the movable end can be attached to the outside of the frame of the two glass doors on the outdoor side by securing the fastener's loop tape 28 and hook tape 28'. If the connection method is other than this, the screen door 2 may be connected by fitting or fastening depending on the configuration.) If the glass door 2 is opened along the rail, the screen door 2
0 are sequentially pulled out from the storage section 30, and both upper and lower guide support plates 1
Guide element 25 along guide rail 14 along 0.10'
Each slides and expands easily.

At this time, the screen door 20 is bent into an accordion shape, and the edges to which the upper and lower guides 25 are attached are fixed by the plate pieces 22, so that the supporting pieces of the guides 25 can be adjusted as the screen door 20 is pulled out.
It rotates on six axes and expands easily, and since the folded portion 21' is curved in advance, it expands in its natural shape without forming any creases.

When the glass door 2 is fully opened, the entire opening is covered by the screen door 20, and when the glass door 2 is half-opened as shown in the first figure, the screen door 20 has a wavy shape depending on the degree of opening. Since the brush portion 23 is provided at the edge of the screen door to cover the entire opening and to the receiving surface 12.12 of both the upper and lower guide supports 10.10', even if the guide rail 14 is interposed Since the receiving surface 12 and the end of the net are always in contact with each other, insects can be prevented from entering and the intended purpose can be achieved distantly.

Then, when the glass door 2 is closed, the screen door 20 moves together with the glass door into the storage section 30, and since the other end is fixed here, it is automatically folded into the storage section 30 and stored in a low volume. It is.

Of course, when the inner glass door 1 is opened, the window is opened and there is no shield of any kind on the outside, so the situation is normal and there is no problem when going in and out of a balcony or the like.

In addition, when the insect screen is not required, such as during the winter, the fixing means on the movable side edges can be released and stored in the storage section, making it easy to dispose of without adding any bulk.

When installing a screen door, if the height is large, for example, if it is used for a large door in a high-rise house or a general house, one or two metal bars should be installed between each plate at the top and bottom of the screen door. Therefore, it is effective to partially attach a net to this in order to provide resistance against opening/closing operations, wind pressure, etc.

As mentioned above, the present invention has a structure in which the screen door can be folded into an accordion shape, and brush parts are provided at both the upper and lower ends of the screen, so that there is always a contact area between the upper and lower edges and the receiving surface of the support body in any situation. The structure is designed to be able to reliably enclose the opening in conjunction with the opening and closing of the door, and to fulfill the role of insect repellent, and the structure is extremely simple so that it can be applied to the outside of the existing window frame. Although it is designed to be easy to install, it does not require a special window sash, and can be easily installed by adjusting the dimensions of each component to match the dimensions of the existing window and fixing the upper and lower supports to the assembled building. Therefore, a reliable screen door can be formed, and its practical effects are great.

Although the upper and lower guide supports in the above embodiments have been described as having separate guide rails, if the guide rails are formed integrally during aluminum extrusion molding so that they do not protrude too much from the receiving surface, the screen door The resistance force applied to the brush part of the brush is reduced, which is convenient, and the cost can be reduced.
